WATER QUALITY INTERACTIONS errors in the pH measurements may have influenced the results. The deep uncontaminated borehole beneath the city centre had a saturation index of –0.8 and a pH of 7.38. These values represent a downward temporal trend, being lower than the results obtained by previous workers (Table 7.4). An upward trend in EC was seen from 290 μScm to 356 μScm between 1988 and 2001. This may indicate increased contamination at depth but the results from the other determinands do not support this conclusively. The results of shallow groundwater sampling showed general saturation with respect to calcite, with an average HCO3 - content of 294 mgl -1 . The piezometers were in general situated on, or adjacent to, open land and would be expected to receive considerable recharge through the soil zone with a high ppCO2 content. The riverbed piezometers showed a mixture of saturation and undersaturation with respect to calcite and the surface water was saturated with respect to calcite. The source of the recharge to the abstraction wells is of significance when considering the active groundwater flow system in the Tame Valley that will ultimately discharge to the river. The lack of any substantial contribution by old calcite saturated water (i.e. the undersaturation) at depth (
